Lymaenon abbreviatus was described from 28 females (including holotype) and 6 males (including allotype), collected in Salta, Jujuy, Tucumán, Santiago del Estero, Buenos Aires, and Misiones Provinces of Argentina as well as in Yacuiba (Gran Chaco Province, Tarija Department) in Bolivia. Altogether, 26 females and 6 males certainly belonging to the type series were found in MLPA. Moreover, some of the following specimens (particularly the females) in MLPA might also belong to the type series (as paratypes) although we treat them as non-types because Ogloblin identified them with a question mark: 1 ♀ on slide labeled: “56. Lymaenon ? abbreviatus [species name ip] ♀ Tigre. B.A. iv.1942.”; 1 ♀ on slide labeled: “ Lymaenon ? abbreviatus [species name ip] ♀ Tigre. B. Aires 11.ii.1945. A. O.”; 1 ♀ on slide labeled: “ Lymaenon ? abbreviatus [species name ip] Tigre. B. Aires III.1945 ”; 1 ♂ on slide labeled: “4. Lymaenon ? abbreviatus A. O. [ip] ♂ Loreto, Misiones 12.ii.1949.”.

Redescription. FEMALE (holotype, paratypes, and non-type specimens). Body length 730–1360 µm. Body mostly yellow or yellowish-orange, trabeculae dark brown, interocellar area light brown; scape and pedicel yellowish or light brown, flagellum dark brown; legs mostly yellowish except metatibia notably darker, light brown to brown; base of gaster pale or light yellow, remainder of gaster yellowish brown to brown.

Head much wider than long, a little wider than mesosoma ( Fig. 176 ). Antenna ( Figs 175 , 178 ) with radicle 0.2–0.24x total length of scape, rest of scape 2.4–2.7x as long as wide; pedicel much longer than F1; F1 the shortest funicle segment and without mps, F2 at least a little longer than F1 and at least a little shorter than F3, F3 either considerably shorter than F4 (when F3 lacks mps and F4 with mps) or just a little shorter to a little longer than F4, F4–F7 usually more or less subequal in length or sometimes F4 a little shorter than F5 (when F4 lacks mps), F8 a little shorter than F7; mps on F2 (usually 0, occasionally 1), F3 (0 or 1), F4 (0, 1, or 2), F5 (2), F6 (usually 2, occasionally 1 or 0), F7 (2), and F8 (2); clava with 8 mps, 3.2–3.7x as long as wide, a little shorter than combined length of F5–F8.

Mesosoma ( Figs 176 , 180 ) a little longer to a little shorter than gaster. Mesoscutum and scutellum almost smooth; propodeum ( Fig. 179 ) with well-developed submedian carinae that widen anteriorly from about midpropodeum and extend almost to anterior margin, smooth between carinae and also between submedian and lateral carinae. Forewing ( Figs 177 , 181 ) 3.3–3.7x as long as wide; longest marginal seta 0.2–0.3x maximum wing width; disc with two brown bands: the smaller, more intensely pigmented band behind and just beyond stigmal vein, and the larger, more uniformly and diffusely pigmented band on the entire apical third or so of wing; bare behind submarginal and marginal veins, sparsely setose behind stigmal vein, and densely setose elsewhere. Hind wing 19–21x as long as wide; disc with a row of setae along each margin and bare elsewhere, with a slight brownish tinge, a little more so just beyond venation and apically; longest marginal seta 2.5–2.7x maximum wing width.

Petiole 1.0–1.2x as wide as long; ovipositor 0.5–0.7x length of gaster, not or just barely exserted beyond apex of gaster; 0.8–1.0x as long as mesotibia.

Measurements (µm) of the holotype. Total body length 953; head 166; mesosoma 400; petiole 40; gaster 363; ovipositor 266. Antenna: radicle 39; rest of scape 149; pedicel 61; F1 30; F2 40; F3 47 (52) [shorter on the left antenna, lacking a mps; longer on the right antenna, with 1 mps]; F4 55; F5 60; F6 55; F7 57; F8 52; clava 218.

MALE (paratypes and non-type specimens). Body length 730–1160 µm. Similar to female except for normal sexually dimorphic features and the following. Body generally a little darker: vertex often entirely brownish (notably more so between ocelli), scape and pedicel light brown, flagellum brown to dark brown; mesoscutum, scutellum, axillae, and dorsellum light brown to brown; apical brown band on forewing disc usually somewhat less pronounced, sometimes more or less as an uniform brownish tinge. Antenna as in Fig. 182 . Forewing ( Fig. 183 ) 3.2–3.5x as long as wide. Genitalia as in Fig. 184 .

Diagnosis. Gonatocerus (Cosmocomoidea) abbreviatus is a member of the ater subgroup of the ater species group, and is characterized by the forewing having two brown bands on the disc ( Figs 177 , 181 , 183 ) and by peculiar submedian carinae on the propodeum that widen anteriorly from about the middle of the propodeum toward its anterior margin ( Fig. 179 ). It can be confused with G. (Cosmocomoidea) mumu sp. n., which has a relatively longer F2 of the female antenna ( Fig. 382 ) and the forewing with distal band on the disc well defined, relatively darker and more distinct basally ( Fig. 385 ), as indicated in the key.

Distribution. NEOTROPICAL: Argentina, Bolivia ( Ogloblin 1953), Brazil *, and Uruguay *.

Hosts. Plesiommata mollicella (Fowler) and Scopogonalia subolivacea (Stål) ( Luft Albarracin et al. 2009), Tapajosa rubromarginata (Signoret) , an undetermined Cicadellini species, and also probably some undetermined leafhopper species on Baccharis sp. ( Ogloblin 1953) ( Cicadellidae ).
